标准范围

IEC 60694:2015适用于通常用于室内使用的电器、电子设备及其部件中的热链路，以保护它们在异常条件下免受过高温度的影响。本标准可适用于在室内以外的条件下使用的热链路，前提是这种热链路周围的气候和其他环境与本标准中的条件相当。本标准可适用于最简单形式的热连杆（如熔化带或熔化线），条件是在运行过程中排出的熔融材料不会对设备的安全使用产生不利影响，特别是在手持或便携式设备的情况下，无论其位置如何。本标准附录H适用于热链路封装组件，其中热链路已通过本标准认证，但封装在金属或非金属外壳中，并配有端子/引线。本标准适用于额定电压不超过690 V交流电的热链路。或者华盛顿。额定电流不超过63A。本标准的目标是:建立热链路的统一要求，定义测试方法，为热链路在设备中的应用提供有用的信息。本标准不适用于在腐蚀性或爆炸性环境等极端条件下使用的热连接。本标准不适用于交流电路中使用的热链路。频率低于45赫兹或高于62赫兹。本第四版取消并取代了2002年出版的第三版、修正案1:20 06和修正案2:20 10。这第四版构成了技术修订。与上一版相比，第四版包括以下重大技术变更:-热链路封装组件的要求；-更新Th-test的要求和定义；-改变中断电流测试的起始温度；-明确标记（包装标签）的要求；-最小证明跟踪索引175而不是120。关键词:设备热防护，热链路

IEC 60694:2015 is applicable to thermal-links intended for incorporation in electrical appliances, electronic equipment and component parts thereof, normally intended for use indoors, in order to protect them against excessive temperatures under abnormal conditions. This standard may be applicable to thermal-links for use under conditions other than indoors, provided that the climatic and other circumstances in the immediate surroundings of such thermal-links are comparable with those in this standard. This standard may be applicable to thermal-links in their simplest forms (e.g. melting strips or wires), provided that molten materials expelled during function cannot adversely interfere with the safe use of the equipment, especially in the case of hand-held or portable equipment, irrespective of its position. Annex H of this standard is applicable to thermal-link packaged assemblies where the thermal-link(s) has already been approved to this standard but packaged in a metallic or non-metallic housing and provided with terminals/wiring leads. This standard is applicable to thermal-links with a rated voltage not exceeding 690 V a.c. or d.c. and a rated current not exceeding 63 A. The objectives of this standard are: to establish uniform requirements for thermal-links, to define methods of test, to provide useful information for the application of thermal-links in equipment. This standard is not applicable to thermal-links used under extreme conditions such as corrosive or explosive atmospheres. This standard is not applicable to thermal-links to be used in circuits on a.c. with a frequency lower than 45 Hz or higher than 62 Hz. This fourth edition cancels and replaces the third edition published in 2002, Amendment 1:2006 and Amendment 2:2010. This fourth edition constitutes a technical revision. This fourth edition includes the following significant technical changes with respect to the previous edition:
- requirements for thermal-link packaged assemblies;
- renew the requirements and definitions for Th-test;
- change starting temperature for interrupt current test;
- clarify requirements for marking (packing label);
- minimum Proof Tracking Index 175 instead 120.Keywords: thermal protection of equipment, thermal-links
